T all whom t may concern:

Be itknown that I, CHRISTIAN IAIAGANs,v

sia, Emperor of Germany, residing at Erfurt,y

in the Kingdom of Prussia, German Empire,

' have invented certain new and useful Improvem ents in Drivin g-'AxlesforLocomotives, of which the following is a specification.

My invention relates to improvements in driving-axlesfor locomotives andis repre-1 sented in the accompanying drawings,Figures l to 8, viz:

Fig. l is a viewand longitudinal section of the driving-axle. Fig. 2 isa front View of the crank. middle of Fig. l of the hollow axle'. Fig. 4is a longitudinal section through the hollow axle and its cross-joint.Fig. 5 isa cross-section of the cross-joint. tion of the lower part ofalocomotive equipped withmyimprovements. Fig. 7isalongitudinal centralsection of'the same', and Fig. Sis a plan view thereof.

It is preferable toconstruct the driving-V' axle T' or'drivinglaxles 'ofthe locomotive,

which arelocated at a distance from the fixed axles, so as to'beadjustable in a radial and movable in a lateral direction. To thisendthe driving-axle -T, Fig.`1, is embraced or surrounded'bya hollow axleH, which carries the Wheels and is `journaled in a revolving frame D,having its fulcrum about the pivot Z. It isthus possible for thelocomotive to travel around sharp curves. The halves of thedriving-wheel axles T are connected to the hollow axle or sleeve H bymeans of a cross-joint, the hollow axle forming the ring of thecross-joint coupling. This form of construction is shown in Figs. 4: and5.

The sleeve His made in one piece. The four pins or pivots of thecross-joint are located side by side, and two pins are arranged at theend of` each =half driving-axle T. VThe halfaxles Tffare--ball-shaped attheir ends el and -Iit in the hollow spherical bearings e c. Each Fig. 3is a section through fthe' Fig. Gis a side eleva-A out at h, and a bodye', worked. out on bothy sides in accordance therewith, isinsertedpbetween the two. On reference to Fig. it will be seen that thebodyjl is seated equally in the correspondingly-formed1recess hin the'ball ends d and thatV the bottoms of said re- In order to transferinoesses are concaved, while the opposite ends of the body e' are conyexedto secure the Ie` sult hereinbefore set forth. The ends of thejoint-pins fare covered by caps 7o, closelytted upon the sleeve l-I tocontain and retain v lubricatingmaterial-for 'the ball-faces d 71,. Eachdriving-axle half T can'easily be removed from the sleeve -H afterthewedges gghave been withdrawn and they cups e' removed. Thelubricatingmaterial is very well protected, and the bearing-faces are securedagainst dust.

Having now particularly described and ascertained the nature ofthisinvention and in Ywhat manner the sameis to be performed, I

declare that what I claim is- 15A device of the class specified,comprising asleeve provided with wheels, an axle consisting of aplurality of sections fitted in the sleeve, and the inner ends of theaxle-sections being ball-shaped and the sleeve being slotted, sphericalbearings in the sleeve for said ball ends, and wedges adapted to projectthrough said slots and to bear against said spherical bearings for thepurpose of adjusting the same.

2. A device of the class described, comprising a sleeve provided withwheels, anaxle consisting of a pluralityof sections lttedinlthe sleeveand having ball-shaped innerends, spherical bearings in the sleeve forsaid ball ends, and the lattervhaving recesses in their adjacentsurfaces, and the bottoms of therecesses being convex, and a body fittedinto said recesses and its opposite ends being ooncave.

3. A device of the class specified, comprising a sleeve provided withwheels, an axle consisting of a plurality of sections inclosed by IOOsaid sleeves and having ball-shaped' innell my hand in presence of twosubscribing Witends, spherical bearings in the sleeve for renesses.ceiving said bali-shaped ends, pins extending,r 1 T 1 through slots inthe sleeve lnd balbshaped CHRIS'I IAB HAGANS' 5 ends respectively, andcaps upon the sieeve Witnesses:

covering the outer ends of said pins. PAUL FRISHMANN,

In testimony whereof I have hereunto set XVILHELM BINDEWALD.
